To what extent does the previous description apply to this patch? In
particular, as regards the ABIs and other features supported. How has
this patch been tested?

glibc does not have per-subdirectory ChangeLog files (except for libidn
and localedata). So ChangeLog entries should contain the full paths to
the files relative to the toplevel glibc source directory, elf/elf.h and
sysdeps/mips/*.h.
I'd expect an addition to sysdeps/unix/sysv/linux/mips/libc-abis for
binary compatibility checks using EI_ABIVERSION to work properly (along
with binutils setting EI_ABIVERSION to 4 when IFUNCs are used for MIPS).
